Hey Benoit,
I believe we'd need to adapt ValidRcptHandler to accept those.
Do you want to give it a try ?
Yes, I can definitely do that. Will open a Jira issue and a PR in the
coming days.
Best regards,
Felix

Nice catch !

As emails to the postmaster address are already rejected after the
RCPT
TO command, the PostmasterAlias mailet is useless when using the
RecipientValidator.
As the postmaster address is mandated in RFC 5321
(https://www.rfc-editor.org/info/rfc5321/#section-4.5.1), I would
propose to add an exception for it in the RecipientValidator.
If that's okay with everybody, I am happy to open a PR for this.
Best regards,
Felix
